Q45 Transmission ID

[DrewQ45]

I'm trying to get a replacement transmission for my 90Q. I've been made to understand that the earlier transmissions have 51x65 or 51x79 stamped somewhere on them with 51x65 being the 90-92 (possibly 93?).

I'm specifically after the 51x65 model. A JDM supplier checked the model # on a 50K transmission and informd me that the metal tag reads "51x05" ... he thinks it's a 94' but is not so sure... Anyone have any idea what model/year that would be and how it might compare to the gearing on a 51x65? The supplier also stated that all the Japanese Market Q45 trannys (except the newer models) are the same gearing...something I find hard to believe. I would also like to know if there is a way to tell the specific year of a transmission since I'm trying to avoid the 1991 models.

Thanks in advance. Drew....

51x79 is 94..... The 51x05 might be like the Z32 transmission, since they used the same transmission... hmmm.

51x10 is the Z32tt transmission.....
